Can anyone out there give me an explanation of why the lower left limb on my killer instinct boss 405 keeps breaking? I’m using the hypo lite 20” 370 grain bolts. I do shoot often. I don’t trust the bow so I’m always making sure everything is squared away. I check accuracy after every hunt. Is it my fault? Am I shooting to much? Is there something I can do to prevent this? I’m very careful when I hunt with this bow. It has never been dropped or banged around! I had a limb break in early October and today November 7th. Needless to say the rut is in high gear here in PA!
I've bought 2 sets of limbs so far I've do e everything I know to do, the limbs are costing so much I could have bought a ten point. I don't know what is going on , I will never buy another killer instinct or Centerpoint period again. ⁹
 
The earlier versions of the killer Instinct limbs are known for slivering or breaking.
These crossbows are manufactured overseas as are the rebranded Rocky Mountain
405 and 415 series, the Bruin Ambush 370 and the no longer manufactured Carbon
Express 390 Pile Driver.
What ever manufacture was building these limbs are using poor quality material or a
poor manufacturing process.

As for Center Point, if one purchases the Sniper XT390 from Bass Pro or Cabela's
one will have a very accurate crossbow at a very reasonable price. This crossbow
is build exclusively for Bass Pro and Cabela's. Absolutely no trigger creep and 3
pounds and under trigger pull. It does not require a trigger job like other Center
Point series crossbows.

Wishing you all the best.
Take care.

Same here . Ive bought 2 sets of limbs. First ones should have been a warranty on them.. I've sent pics an nothing.. idk if its worth me putting another set on the bow. First time i shot it an it cracked. I'd like to know why, but never get a answer.

I would keep emailing and calling until it's resolved. You purchased the bow and submitted info for warranty so they need to take care of it. Ask them about upgrading or a refund too, seems like certain models of KI bows are destined for limb failures

370 grains of total arrow weight is easy too light for a 405 bow. They really should have never put those arrows in the package
 
Well I’m on my 2nd KI, and my kids were just shooting and the limbs cracked. I will be on my 3rd I guess. I have not had great luck with the crossbows, but their customer service is great so far. I will call 1st thing in the morning. Hopefully they take care of this issue again. Bad thing is they are tack drivers and I hate to venture off if they don’t take care of it.

using 22" pile drivers 450g with 100g broadheads . These crossbolts are a bit pricey but it's cheaper than replacing limbs every other week. Bow assembly bolts no longer vibrate loose using blue lock tight . Sofar no cam issues . Sighted the factory scope in by using laser tipped bolt . Had to compensate for the heavier arrows but so far she's dead on. And made some cosmetic changes to suit my style of shooting. Little over 6 months of target practice once a week . No problems so far. But these post about so many problems reported have me a bit Leary of trusting her .
 
I'm in the Killer Instinct Customer Service Phone Hold Limbo. Bought mine less than 2 weeks ago. This is my first crossbow, and I've wanted one for a long time. I'm disappointed. This is what I've learned:

Buy from a store. Crossbows have issues. I want someone who can help if something comes up.

I don't know how I'm going to tell my wife that my crossbow has issues. I had to convince her it was something worth spending money on. We're retired and we are not rich.

I'm asking the same question the right side limb Crack called killer instinct headquarter a lot of question ,when you did you buy it,got your receipt ,did you registered it life time warranty my ass they know the 405 is a piece of junk
 
For crossbow manufacturers to get their advertised speed is why they list the lighter arrow
point combinations but most due not recommend shooting that light.

Killer Instinct crossbows are manufactured overseas and who ever is building the limbs are not
using high quality material, poor glue or not being cured properly.

I had a different brand, built over there with limb problems. The limbs would either splinter
or the last replacement had 56 shots where a limb actually broke. I always shoot arrow-point
combinations of 430 to just under 500 and it did not make any difference.

Some crossbows have very high recoil that can easily damage good quality rifle scopes. To
make these crossbows lighter the manufacturer uses composite stocks that parts are hollow
and filled with a foam substance.
When an importer is willing to purchase large amounts with the hope of selling them, they can
can buy a lot cheaper and sell cheaper and easily offer replacement parts.

Wishing you all the best.
Take care.
 
Where do I get these so called limbs ? I've looked and it's hard to find these anywhere. I found a new KI 405 crossbow brand new with only a left cracked limb...can anyone help a bum out?
KI will not sell limbs directly to the customer any more but will send them to a dealer. If you have one close you can check with them if not I know some have bought them from Wyvern Creations so you could check with him.
 
I’m going to pick up a Barnett TS380 in the morning! So you don’t think it has anything to do with me? Like shooting to much? I’m shooting the bolts that came with the bow and I just bought 6 more!
Definitely go to a way heavier bolt if you can look around Dunham's sporting goods has great prices on the killer tech bolts which are 430 grains with 100 grain tip the ones that you're shooting with it are 370 grains they're way too light and I can't absorb enough energy therefore it causes the limbs to absorb energy you should be shooting at least 450 grains total if possible I shoot the killer text with 125 grain broadheads so that puts me at 4:55 to 460 but I've also shot pile drivers carbon Express white tails blood sports depending on which bow I'm shooting I have 7 Killer Instinct crossbows right now and I use anywhere between a 500 grain and a 455 grain bolt
